5 packing it is essential that the waste and the oil parts be separated so that both parts may be properly renovated thereafter, and the renovation or reclamation ci the former part, to Wit, the waste part, is the one with which this application is concerned. IThe inbound dirty packing contains many undesirables such as line lint, in suspension in the oil and mingled with the waste lfibers, dirt of all kinds, short ends oi fibers, metal vfragments, and many other varied types of impurities. As will be readily understood, all or these impurities must or at least should be removed. Some oi them pass out with the oil part when it is separated from the waste part but others thereof remain with the Waste part, furnishing contamination therefor aside :from giving it a dirty, unsightly color or appearance. f

The object oi the present invention therefore' is to provide apparatus for performing the steps of separating the oil and waste parts and o/thor`= oughly cleansing the latter, ready for the rernoval therefrom, ii necessary, of such undesirables as heavy pieces of dirt, grit or metal. The invention contemplates also the oil washing or scrubbing of the waste fibers to restore their former color and 'to render ther-n as good as, indeed better than, new waste in that most of the short ends and -Sine lint are removed.

stated, the apparatus consists of an e= tractor type o device including a vertically disposed rotatable basket for receiving the packing and having an undulating, corrugated or fluted wall presenting vertical ridges and valleys adapt= ed to support the packing in an unmatted, porous condition to permit the :tree circulation through and discharge from the packing not only of the oil originally contained therein but also, additional hot oil furnished for the purpose o washing out and removing substantially all traces of the old oil, and substantially all of the undesirables, such as lint, dirt and the like, leaving the waste part with substantially ber saturation only and ready for impregnation with new or renovated oil.

The invention is set forth in the following description, drawings and claims.

Referring to the drawings, Fig. l is a top plan View of a portion oi a packing reclamation plant; embodying the apparatus forming the subject matter or the present application; Fig. 2 is a front elevation thereof; Fig. 3 is a view partly in top (Cl. Zilli-66) plan and partly in section showing the extractor basket; Fig. d is a View of the basket partly in side elevation and partly in section; Fig. 5 is a ver-l tical section through the distributing device arL1 ranged at the center of the basket; Fig. 6 is a so cross section upon the line 6 6 of Fig. 5; and Fig. 7 is a cross section. upon the line 7 7 oi? Fig. 5.

ln the embodiment shown, l represents a drain age tank connected by a discharge pipe 2, either es with an underground sump generally indicated at 3 or with an oil renovatingplant, not shown. This tank has an upper grid d upon which the,

,inbound dirty packing is placed and any free oil present in the packing drips into this tank. Ex- 7o tending from both ends o this tank are drain boards 5 draining back to the tank and extending to extractor type, oil treating devices.

There are two of these extractor devices and since they are oi identical construction a descrip- 7d -tion of one will suice for Each comprises a lower support 6 and a curb? connected at the bottom to suitable drainage pipes il leading to a main drain 9 in turn leading to the dirty oil sump 3. fore rind its way to the dirty oil sump. Each o the extractors has suitable bearings, not shown, for supporting an extractor shaft lll, Figs. 3 and and upon this snai;I is mounted a basket bottorn ll carrying at the center a distributor base 85 l2 supporting a central cylindrical Ydistributor lS partially closed at the top by a flange lll.- and provided in its side wall with vertically disposed, circumferentially arranged slots l5. These slots,

which are arranged in staggered relation, as 9@ shown, increase in width from the bottom toward the top of said wall/that is, the higher the slots the wider they are, whereby oil supplied to this distributor will be distributed evenly in a radial direction Within throughout the height of the packing therein.

Secured to the periphery of the extractor basket bottom 1l is a perforated basket side wall 16 connecting Aat its top to the usual extractor basket top ange 17. Within this wall E001 and supported by it is the means for preventing undue matting or compressing of the brous waste part, said means being shown in the present embodiment as in the form of a uted wire mesh lining 18. The flutes are spread, as shown, w53

to providea multiple pointed star arrangement in cross section, the object being to present to the packing an undulating wall in the form of vertical ridges and valleys which will support the material, prevent its packing and matting, and H0 Any oil deposited in the curb 7 will there e@ the extractor basket and e5 provide the maximum of discharge area for any oil or any undesirable material in the fibrous waste part. As is usual, each extractor is provided with a suitable cover, indicated at 19, Fig. 1, and having a central opening 20 therein for the reception of an oil supply pipe 2l connected to an oil supply line 22. This pipe projects down through the opening 20 and into the central opening of the flange 14 of the distributor. In order to heat the oil to the proper extent for oil removal and waste washing purposes, the line 22 may lead from an indirect heaterv 23 provided with a primary steam circulating heating coil 24 arranged therein.

In use the inbound dirty packing is loaded into the basket of the extractor from the drainage grid 4 and drain board 5 and the basket is rotated at a moderate speed, say 800 to 900 R. P. M. This speed is insufcient to pack or mat the packing at the periphery of the basket in view of the undulating lining 18. If the oil of the packing is sufficiently fluid to pass out as a result of rotation at this speed it may do so, and some usually does but ultimately hot dirty oil or hot clean oil is supplied to the distributing member in the manner theretofore disclosed and is caused to forcibly and uniformly pass through the interstices of the packing, mingle with the oil therein, and pass out with it into the curb. As this oil washing operation is continued, the fibers of the waste part of the packing are thoroughly scrubbed and any moisture present in the waste part and indeed in the oil part is vaporized and passes off. After treatment in this way for a sufficient length of time, the fibrous waste part is left clean and entirely rid of water moisture. In order to reduce the oil content of the waste part, the supply of oil is cut off and the basket driven at a higher speed, if desirable, to thereby reduce the oil content of the waste part to ber saturation only and to remove all free oil deposits in the interstices of the waste part. If desired,

f clean oil supplied to pipes 25 from any suitable source of clean oil supply may be passed through the waste part to change the films of oil forming the ber saturation to clean removed oil film. It is quite obvious from the foregoing that the entire lint content of the waste is carried away with the oil leaving the waste part entirely lint and dirt free, it only being necessary in some cases to afterwards tumble vthe waste, as is the usual practice other undesirables present, if any, such as large bits of metal, etc.
